Carbuncle, The Ruby Stone

l had from this most wealthy queen 
 A beast of proud and noble mien 
 That bears in his brow the ruby-stone 
 And yields himself to maids alone. 
But few such Unicorns are found 
 On this or any other ground, 
And only such are ever captured 
As pure virgins have enraptured. 
 No man yet of woman born 
   Endures the terror of his horn.
